安捷伦48902020版药典二氧化碳分析玻璃球色谱柱HH-BLQ

中国药典2020年版

5年一次的药典换版，都得到了行业的高度关注。2020版药典因为中药材重金属、农残检验问题，行业高度的关注。

碳氢化合物照气相色谱法(通则0521)测定供试品气体取本品,即得对照品气体取甲烷含量为0.0020%的气体(以氮气为稀释剂)。色谱条件用玻璃球为填料的色谱柱(4mm×0.8m,80目);柱温为110℃;进样口温度为110℃;检测器为火焰离子化检测器,温度为120℃测定法精密量取供试品气体与对照品气体,分别注入气相色谱仪,在净化温度为360℃时测得的峰面积为相应空白值;精密量取供试品气体与对照品气体,分别注入气相色谱仪,测定峰面积,减去相应空白值后的峰面积为校正峰面积限度按外标法以校正峰面积计算,含碳氢化合物(以甲烷计)不得过0.0020%。

浩瀚色谱（山东）应用技术开发有限公司，采用新技术，依据2020版药典二氧化碳的指标要求研制生产HH-BLQ玻璃球色谱柱，在安捷伦4890气相色谱仪上安装测试完毕，运营正常，效率高，结果满意，受到用户的好评。
Chinese Pharmacopoeia 2020 Edition
The revision of the Pharmacopoeia every five years has received great attention from the industry. The 2020 edition of the Pharmacopoeia is highly concerned by the industry due to the inspection of heavy metals and pesticide residues in Chinese medicinal materials.

Hydrocarbons are measured by gas chromatography (general rule 0521) and the gas of the test product is taken from this product, that is, the gas with a methane content of 0.0020% is obtained as the reference gas (with nitrogen as the diluent). Chromatographic conditions: Use a chromatographic column (4mm × 0.8m, 80 mesh) with glass balls as filler; the column temperature is 110°C; the inlet temperature is 110°C; the detector is a flame ionization detector, and the temperature is 120°C. Measure the test gas and the reference gas, inject them into the gas chromatograph respectively, and the peak area measured when the purification temperature is 360 °C is the corresponding blank value; accurately measure the test gas and the reference gas, and inject them into the gas chromatograph respectively. Instrument, measure the peak area, and the peak area after subtracting the corresponding blank value is the calibration peak area limit. Calculate the calibration peak area according to the external standard method, and the hydrocarbon content (in terms of methane) shall not exceed 0.0020%.

Haohan Chromatography (Shandong) Application Technology Development Co., Ltd. adopts new technology and develops and produces HH-BLQ glass sphere chromatographic column according to the requirements of the 2020 edition of the Pharmacopoeia for carbon dioxide. It has been installed and tested on the Agilent 4890 gas chromatograph. The results are satisfactory and well received by users.
